Appendix one illustrates the timeline for laboratory testing of samples for the production of Pre-Elite seed potatoes from sources other than Nuclear Stock. Following harvest of samples in the fall, two alternatives for disease testing are illustrated. In one scenario all disease testing takes place in the winter months, and if results allow, planting may take place in the spring. In the second scenario, Bacterial Ring Rot testing takes place in the winter months, followed by testing for other diseases on individual plants in the field following spring planting. In the second scenario, if results allow, the field is eligible for Pre-elite status.
